Aluminum CNC Milling Service

Aluminum CNC Milling Service is a machining process that involves the use of computer numerical control (CNC) machines to remove material from an aluminum workpiece. It is a precise and efficient method for creating complex shapes and parts from aluminum.

 

What is the process of our aluminum CNC milling?

1. Design: Send us your design (CAD file or 3D files) or Samples.

 

2. Programming: After checking customer's drawings, our programmer begin to programming for the CNC milling machine. This program includes instructions for the machine to follow, such as tool paths, cutting depths, and feed rates.

 

3. Material Setup: The aluminum workpiece is securely clamped or fixtured onto the CNC milling machine. 

 

4. Tool Selection: Choose suitable cutting tools, such as end mills or ball mills, are chosen based on the design requirements and the desired finish.

 

5. Milling Operation: The CNC milling machine precisely moves the cutting tools along the programmed tool paths to remove material from the aluminum workpiece. The machine's spindle rotates the cutting tool at high speeds, cutting into the workpiece to create the desired shape or features.

 

6. Finishing: Once the milling operation is complete, the part may undergo additional processes like deburring, polishing, or surface treatment to achieve the desired surface finish.

 

7. Inspection and Quality Control: The finished part is inspected to ensure it meets the specified dimensions and tolerances. we have different measuring tools such as calipers or coordinate measuring machines (CMMs).

 

8. Delivery: Once the part passes inspection, it is ready for delivery to the customer.

 

We can provide CNC milling services. We have the necessary expertise, equipment, and software to handle aluminum milling projects efficiently.

When you seeking an aluminum CNC milling service, contact us with your specific requirements, including dimensions, tolerances, surface finish, and quantity needed. This will help us deliver the desired results effectively. And, do not worry about the turnaround time, cost, secondary operations, we will meet all of your requirements.

 

 

Knowledge of aluminum CNC milling

Aluminum is the most used non-ferrous metal, the most widely used metal material, and its application range is still expanding. The use of aluminum production of aluminum products is a wide variety of different needs from the construction and decoration industry to the transportation industry and aerospace and other industries. Today, I would like to introduce you to the surface treatment of aluminum products. 

The superiority and characteristics of aluminum are as follows. 

1,Low density. The density is only about 2.7g/cm3, which is only 1/3 of that of iron or copper.

2,High plasticity. Aluminum has good ductility and can be made into various supplies by extrusion, stretching and other pressure processing means. 

3,Corrosion resistance. Aluminum is a very negative metal, in natural conditions or anodic oxidation of the surface will generate a protective oxide film, with much better corrosion resistance than steel. 

4,Easy to strengthen. The strength of pure aluminum is not high, but its strength can be improved by anodic oxidation. 

5,Easy surface treatment. Surface treatment can further improve or change the surface properties of aluminum. Aluminum anodizing process is quite mature, stable operation, and has been widely used in the process of aluminum products. 

6,Good electrical conductivity, easy to recycle. 

Surface treatment of aluminum CNC milling products

1. Sandblasted (shot blasting)

The process of cleaning and roughening metal surfaces using the impact of a high-speed sand stream. This method of surface treatment of aluminum CNC milling Service parts enables the surface of the workpiece to obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved, therefore increasing the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, extending the durability of the coating film, and also facilitating the leveling and decoration of the coating. This process we often see in various products of Apple.

 

 

2. Polishing

The use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece, in order to obtain a bright, flat surface processing methods. There are different method for the polishing, such as chemical polishing, mechanical polishing, electrolytic polishing. Aluminum parts using mechanical polishing + electrolytic polishing can be close to the stainless steel mirror effect, the process, giving a high-grade simple, fashionable future feeling. 

 

3. Brushing

Metal brushing is a manufacturing process in which lines are repeatedly scraped out of aluminum sheets with sandpaper. Brushing can be divided into straight brushing, messy brushing, rotary brushing, and thread drawing. Metal brushing process, can clearly show every fine trace, so that the metal matte in a fine hair luster, the product is both fashion and technology.

 

 

4. High-gloss cutting

The diamond cutter is reinforced by a precision engraving machine in a high-speed rotating (generally 20,000 rpm) precision engraving machine spindle to cut parts, producing a local highlight area on the product surface. The brightness of the cutting highlight is affected by the speed of the milling drill, the faster the drill speed the brighter the cutting highlight, and vice versa, the darker and easier to produce knife patterns. High light cutting in the use of cell phones in particular, such as the iphone5, in recent years, some high-end TV metal frame using a high-gloss milling process, coupled with anodic oxidation and brushing process makes the phone overall full of a sense of fashion and technology sharpness. 

 

5. Anodizing

Anodizing is the process of forming a layer of oxide film on aluminum products (anode) under the action of an applied current in aluminum and its alloys under the corresponding electrolyte and specific process conditions. Anodizing can not only solve the defects of aluminum surface hardness and wear resistance, but also prolong the service life of aluminum and enhance the aesthetics, which has become an indispensable part of aluminum surface treatment.

 

 

6. Two-color anode

Two-color anodizing is the process of anodizing a product and giving a different color to a specific area. The two-color anodizing process is less commonly used in the TV industry because of the complexity and high cost of the process; however, the contrast between the two colors better reflects the high-end, unique appearance of the product.
